Treatment #1 - Salt Dip
Add salt to water at 10 tablespoons per gallon or 5 pounds per 25 gallons. Place fish in this solution for ninety seconds. The fish will turn white and roll over like it's dying, but will quickly recover when returned to fresh water. This will quickly remove any microscopic parasites.
Treatment #2 - Salt Bath
We maintain salt in our holding facilities at 0.3%. This is obtained by adding 3 teaspoons per gallon or 25 pounds of non0iodized salt per 1,000 gallons over a 48 hour period. Some Costia strains can require up to .6% to eradicate. An accurate digital salt meter can be purchased for under $80 at most koi dealers and dry goods retailers.
Treatment #3 - Praziquantel
Praziquantel (brand name Prazi Pond) is effective to treat flukes on goldfish and koi.
Treatment #4 - as directed, use Broad Spectrum
